Optical module-The transmission distance and the application scenario

The short-distance optical module generally refers to the optical module with a transmission distance of less than 2km and a wavelength of 850nm. It is mainly used in short-distance transmission scenarios such as the equipment room, HDNI optical terminal machine, and SDI optical terminal machine, and is connected to multi-mode optical fibers with a fiber diameter of 50/125um or 62.5/125um.

The transmission distance of the Medium distance?optical module is generally between 2km and 30km.

The long-distance optical module refers to the optical module with a transmission distance of more than 30km, which can meet the needs of long-distance network data transmission.?For example, it is widely used in server ports, switch ports, network card ports, security monitoring fields, telecommunications fields, Ethernet, synchronous optical fiber network a and other fields.

120 km optical module refers to optical fiber communication equipment components that can transmit data over a distance of up to 120 km, mainly used in long-distance optical communication systems. Such optical modules typically use single-mode fiber as the transmission medium, and are equipped with high-performance laser transmitters and receivers to ensure that the quality and integrity of the signal over such a long span is not significantly lost.

?

In order to solve the dispersion problem of optical signal transmission in optical fiber, DFB laser with only one main wavelength is usually used as the light source.

In different types of optical modules SFP + optical module uses EML laser components and optical detector components, while reducing the power consumption of optical modules, but also improve the accuracy;

Long distance 40G optical module In the transmission link, such as SFP optical module, SFP+ optical module, XFP optical module, 25G optical module, 40G optical module and 100G optical module, there are long distance optical modules.

The driver and modulation unit are used for long distance, and the optical amplifier and photoelectric conversion unit are used in the receiving link to achieve a maximum transmission distance of 80km.

?

However, the transmission distance of the optical module is not the farther the better, and the appropriate optical module should be selected according to the actual networking situation to meet different transmission requirements.

(1)short-distance optical modules

In the data center, short-distance optical modules can be used for short-distance connections between servers to meet the needs of fast internal data transmission.

The short-distance optical module is generally connected to a multi-mode fiber with a fiber diameter of 50/125um or 62.5/125um for data transmission, and is sent in a refraction mode, which can only send a signal of one wavelength, and cannot be sent in two wavelengths in different directions on an optical fiber, and can only run on a multi-mode fiber, and cannot be used with a multiplexer.

(2) Medium distance optical module

Medium range optical modules usually have better signal stability and transmission efficiency.

In the medium and long distance transmission scenario of the data center, the medium distance optical module can meet the data transmission requirements within a certain range, for example, the server connection between different floors or different areas.

Mid-range optical modules may employ some special techniques to reduce signal attenuation and dispersion to ensure accurate data transmission.

Its characteristics include moderate transmission distance, high cost performance, etc., which is suitable for scenarios that have certain requirements for transmission distance but do not need long-distance transmission.

?

(3) Long distance optical module?

Long range optical modules are widely used in server port, telecommunication, Ethernet, synchronous fiber network and other scenarios.

For example, in the telecommunications field, including data control centers and computer rooms, long-distance optical modules can realize long-distance data transmission to ensure stable and efficient communication.

In the field of security monitoring, the long-distance optical module can transmit the monitoring picture to the control center in real time to improve security.

In the fields of Ethernet and synchronous fiber networks, long-distance optical modules also play an important role to meet the needs of long-distance network data transmission.
